UNITED STATES PATENT OFFICE.

JOHN HUBBELL, on NEW YORK, N. Y.

IMPROVEMENT IN SCREEN-HOLDERS FOR LAMPS.

Specification forming part of Letters Patent No. 189,224, dated April 3,1877; application filed February 22, 1877.

To all whom it may concern:

Be itknown that I,.JoHN E. HUBBELL, of the city, county, and State ofNew York, have invented a new and Improved Screen-Holder for Lamps,which invention is fully set forth in the following specification,reference being had to the accompanying drawing, in which the figure inthe accompanying drawings illustrates a students lamp having my improvedscreen-holder applied thereto according to my invention.

Similarletters indicate corresponding parts.

My invention relates to a screen-holder which is designed to be.attached to a lamp, either permanently or temporarily, so that it isalways available or ready for use, and not liable to become misplaced.It consists in a bracket, which is so constructed that it can be firmlyattached to a lamp and detached therefrom at pleasure, and which carriesa horizontal arm of such form that a screen can be secured thereto insuch a manner that the screen is held in a vertical position in front ofthe lamp to which the holder may be attached, the construction of thebracket and its attachment to the lamp-standard being fully hereinafterdescribed.

In the drawing, the letter A designates the bracket, and B is thehorizontal arm, com posing my improved holder. The bracket A is made oftwo arms, a a which are riveted or otherwise fastened together, andconnected by a brace, a One of the arms a a is provided with an eye, I),at its inner end, while the other arm is bent to form a hook, c, at saidinner end. This construction of the bracket A renders it applicable to astudent lamp, andwhen it is applied to this class of lamps the head ofthe standard 0 of the lamp is unscrewed, and

The bracket A is thus firmly attached to the lamp, while it can bedetached therefrom at will.

The horizontal arm B is riveted to the arm a of the bracket A, orsecured thereto in any other suitable manner, and in said horizontal armB are formed a series of holes or perforations, d, to permit ofconnecting thereto a screen, D. The holes or perforations d extendthroughout the entire length of the horizontal arm 13, and the screen Dis secured to the arm by means of rivets passed through the perforationsd; but it is obvious that the screen D can be affixed to the horizontalarm B in various other ways than the onejust described, and I do notwish to limit myself to any precise means for effecting this object.

What I claim as new, and desire to secure by Letters Patent, is-

A screen-holder for lamps, composed of the bracket, constructed of thearm a inclined arm a and horizontal arm B, having the screen D attachedthereto, the arms a and'a. having the eye I) and hook c, for securingthe bracket to a lampstandard, the whole being combined substantially asand for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 20th day of February, 1877.
